This option is for WordPress users that their blog is hosted on Windows server. It might possibly be that there is an error with Directory Indexes.
Go to your Cpanel, locate and click on Web Options. Go to Directory Indexes, add index.php to the Directory Indexes.

This is another common WordPress error that usually happen when you are trying to insert code snippets to your functions.php file. The message is telling you that there is an error in your code that needs to be corrected.
Solution :
  • Since the browser will tell you the exact file with issue and the line the parsing error occurs, connect to your site via FTP and remove the line of code.
When you see a message like this on your browser “Fatal error: Call to undefined function get_header() in /example/site/wp-content/themes/yourtheme/index.php on line_14, this is as a result of plugin conflict.
In most cases, the fatal error will always tell you the problem and in which file. It is very easy to interpret just looking at it alone. The above example tells us that the fatal error was caused by a theme using a function hook.
Solution :
  • If you know how to code, you can check the file indicated and solve the problem.
Sometimes the solution to most of these WordPress errors are just either increasing the PHP memory limit, deactivating and reactivating them one after the other, deactivate current theme to default, or fix corrupt .htaccess file.
